Two new species belonging to the genera Microdrosophila and Drosophila, collected from Daegwallyeong and Mt. Halla in Korea are described with illustrations of the male genitalia. Microdrosophila (Microdrosophila) gangwonensis n. sp. seems close to M. (M.) purpurata Okada, 1956, but the new species has different phallic organ. Drosophila (Drosophila) taekjuni is close to D. (D.) brevitabula Zhang and Toda, 1992, in form, but differs in the shape of aedeagus. Eight species of the genus Microdrosophila and five species in the D. immigrans species-group of genus Drosophila, including the new species are known to be distributed in Korea.

Fifteen species of water mites belonging to the genus Atums are reported from the eastern area of Korea, with the following five of them described as new species: Aturus glaberus, A. parauarus, A. quodrotus, A. sankveriensis, and A. trifurcatus, n. sap. A. complexus Sokolow and A. tewaconfusensis Habeeb, both new records for Korean fauna, are re-described.

During a Korean mushroom diversity survey from 2011 to 2014, we found one new Xylaria species (X. ripicola sp. nov.) and one Xylaria species that had not been previously observed in Korea (X. tentaculata). To confirm the phylogenetic placement of the new species, we conducted a phylogenetic investigation based on internal transcribed spacer regions of ribosomal DNA sequences. Additionally, the new species, X. ripicola, was subsequently analyzed for RNA polymerase II subunit sequences. We also evaluated the macroscopic and microscopic features of this species. Herein, X. ripicola is described as a new species that was collected from a natural beach habitat and X. tentaculata is formally reported as newly found in Korea.

A new species of the cave-dwelling springtail Lethemurus coreanus Chang and Bae, sp. n. is described from Korea. Lethemurus coreanus can be distinguished from congeners by the spine-like setae on the tibiotarsus, numbers of dental spines, number of setae on the trochanteral organ, and body macrochaetae chaetotaxy. A key to the species of Lethemurus is provided.

The present study summarizes the occurrence, distribution and autecology of 12 taxa of the class Cyanophyceae collected from several swamps, reservoir and highland wetlands in South Korea from 2009 to 2012. A new species, Anabaena koreana sp. nov. and 11 taxa of blue-green algae newly recorded are described and illustrated. Anabaena koreana is similar to A. oumiana, A. spiroides and A. crassa in that the trichomes form regular coils. However, A. koreana is distinguished from these three species by the morphological characteristics of the vegetative cell, heterocyst, and akinet shape and size. This study considers 12 blue-green algal species, including a new species, Anabaena koreana sp. nov. and 11 species that are recorded for the first time in the Korean freshwater algal flora. Among them, the genus Nostochopsis Wood ex Bornet et Flahault 1886 had not previously been recorded in Korea.

The morphology of 26 species of the genus Tripos was studied among a total of 51 species of this genus, which were taken using $20{\mu}m$ net samples from June 2006 to January 2011 at 14 stations around Jeju Island. Of these, 23 species were first described as new records in Korean waters and 3 species were redescribed. Short descriptions and synonyms are given for each species in the present study. The dinoflagellates of family Ceratiaceae include marine and freshwater species, belonged to originally the genus Ceratium. Recently, this genus were divided into a new combination with the genus Tripos, which contains the marine species, and the original genus Ceratium, including the freshwater species. We used the Tripos genus for the marine species in this study as a valid name.

A taxonomic study on the genus Tropocyclops has been accomplished as a part of the series of studies on the freshwater cyclopoid copepods in South Korea. As a result, the Tropocyclops prasinus, hitherto known from Korea in many reports and papers, turns out to be a species complex of three sibling species: T. prasinus (Fischer, 1860), T. ishidai n. sp., and T. setulifer n. sp. This paper deals with description of two of these new species with taxonomic accounts on their inter- or intraspecific morphological discrepancies.

Four species of the genus Exochus belonging to the subfamily Metopiinae, family Ichneumonidae, are reported in South Korea for the first time. The subfamily Metopiinae was recorded by Förster in 1869 based on genus Metopius and more than 870 described species have been reported worldwide. Among the genera of Metopiinae, genus Exochus is the largest, which is cosmopolitan and comprises more than 290 described species worldwide (Choi et al., 2016; Yu et al., 2016). A taxonomic study of South Korean Exochus was initiated by Choi et al. (2014), who reported four species. Until now, 10 species have been described as new species and 25 species were recorded as new records of this genus from South Korea (Choi et al., 2014, 2016). In the present study, the following four species are reported in South Korea: Exochus latiareolus Tolkanitz, 2003, E. ornatus Momoi & Kusigemati, 1970, E. pictus Holmgren, 1858, and E. yasumatsui Momoi, Kusigemati & Nakanishi, 1968. In addition, we provide the diagnoses of these four species along with diagnostic photographs.

One new species and six unrecorded are described with illustrations based on the specimens collected in 1970s-1990s in Korea. The genera Phaenopsectra, Xenochironomus, and Smittsia are reported for the first time in Korea.
